<span>a = 25-13/6 = 12/6 = 2 m/s^2
Av speed: 25+13/2 = 38/2 = 19 m/sec
Dist = speed * time
19 * 6 = 114 meters</span>
Answer:
11m/s
Explanation:
Given parameters:
Mass of the lead shot = 8kg
Energy of the shot = 484J
Unknown:
Velocity of the shot = ?
Solution:
To solve this problem, we apply the kinetic energy formula;
K.E =
m v²
m is the mass
v is the unknown
Now, insert the parameters and solve;
484 =
x 8 x v²
484 = 4v²
v² = 121
v = 11m/s
Answer:
dV = 32.98 cm³
Explanation:
We know that
V = f ( h,r)

We also know that


Given that
h= 10 cm
d=10 cm , r= 5 cm
Thickness = 0.05 cm so dr = 0.05 cm
The metal in the top and the bottom is 0.2 cm thick so dh = 0.2 + 0.2 cm
dh = 0.4 cm
Now by putting the values


dV = 32.98 cm³
